Last winter I published a series of charts in which I compared popular ed tech tools for things like blogging, informal assessment, and video production. As is to be expected in the tech world, some of the tools in those charts have changed. Therefore, I’m now going through each chart and updating it.

Yesterday, I published an update to my blogging platforms comparison chart. Today, I updated my chart comparing tools for backchannels and informal assessment. The most notable difference in this chart compared to the previous version is the removal of Infuse Learning which shut down in April and the addition of Formative. The updated chart can be seen as a PDF embedded below. You can get a Google Docs version of the chart here.
